The present invention relates to a method for manufacturing an electric heating pipe that includes a step for preparing a pipe(10), a step for preparing a pipe installation body by successively inserting a U-shaped heating line(20) into the through hole of a first insulating formation body(31) and a second insulating formation body, a step for inserting the pipe installation body into the pipe(10), a step for inserting a silicone cover(40) into one end of the pipe(10), a step for filling the pipe with an insulating material(60), a step for inserting a terminal part(70) into the other end of the pipe(10), a step for reducing the diameter of the pipe(10) by a roller for reducing the diameter of the pipe after the insertion of the pipe installation body, the insertion of the silicone cover(40), the filling of the insulating material(60), and the insertion of the terminal(70) are completed in the pipe(10), and a step for pressuring and fixing the cover(50) to the end of the diameter-reduced pipe(10). [Reference numerals] (AA) Prepare a pipe;(BB) Prepare a pipe installation body;(CC) Insert the pipe installation body into the pipe;(DD) Insert a silicon cover into one end of the pipe;(EE) Fill the pipe with an insulating material;(FF) Insert a terminal part into the other end of the pipe;(GG) Reduce the diameter of the pipe by a roller;(HH) Pressurize and fix the cover to the end of the diameter-reduced pipe |
